7 Key Factors & Practical Guide.
1. Technical Qualification Verification
- Certifications: Require ISO 9001 + EN81-20/50 + local permits (e.g., China TSG T7001)
- Patents: Prioritize suppliers with core technologies like PMSM gearless traction (30-40% energy saving)
- Project Portfolio: Verify ≥3 similar project cases (e.g., hospital medical elevators)
2. Lifecycle Cost Analysis
| Cost Type | Chinese Supplier | European Supplier |
| Equipment | $35,000 | $65,000 |
| Installation | $8,000 | $15,000 |
| 10-Year Energy | $12,000 | $18,000 |
| Annual Maintenance | $1,200 | $2,500 |

3. Smart Maintenance Capabilities
- IoT Monitoring: Real-time sensors (120+ parameters) + predictive maintenance (≥95% accuracy)
- Emergency Response: 30-min phone response + 4-hour on-site service commitment
- Digital Tools: Mobile APP for elevator health monitoring (e.g., KONE E-Link)
4. Customization Compatibility
- Space Adaptation: Verify non-standard shaft solutions (e.g., 1.2m×1.4m narrow shafts)
- Scenario Optimization: 30-min phone response + 4-hour on-site service commitment ( Hospitals: ≤±5mm leveling accuracy (for stretcher transport) & Industrial Zones: ≥16-ton capacity elevators (see Shengho case) )
5. Sustainability Metrics
- Energy Certification: ENERGY STAR preferred (25%+ energy saving)
- Material Safety: RoHS compliance reports (heavy metals ≤0.1%)
- Carbon Tracking: Full lifecycle emission data sheets
6. Contract Risk Management
- Legally binding technical specifications
- Late delivery penalties (0.1% daily of contract value)
- 10-year warranty for core components (traction machine/control cabinet)
7. Market Reputation Audit
- Third-Party Verification:Google Business Rating ≥4.5 (50+ reviews) & Zero accident records on official platforms
- Client Reference Checks: Request 3 existing client contacts
